Food And Beverage Server

ABSTRACT

A food or beverage server includes a container having a body with a sidewall, a base, and at least one external engagement element on the sidewall or the base. A thermal core includes a hollow body with at least one internal engagement element for engaging the at least one external engagement element on the container to retain the thermal core on the container. The hollow body has a central portion for heat-transfer with the base of the container and a thermal medium, such as a saline solution, refrigerant, water, oil or sand, within the hollow body.

This application is a continuation-in-part of application Ser. No. 13/325,923 filed Dec. 14, 2011, the disclosure of which is incorporated herein by reference.

The present disclosure is directed to a device to help maintain a cool temperature in a food or beverage product such as beer, wine or soda or a warm temperature in coffee, for example, after the food or beverage has been removed from a chilling or heating environment.

BACKGROUND AND SUMMARY OF THE DISCLOSURE

A general object of the present disclosure is to provide a device for securement to the bottom of a food or beverage container, such as a glass bottle, which can be readily chilled to a low temperature such as in a cooler or freezer, or heated to elevated temperature such as in a microwave, which can be readily assembled to a container, and which will draw heat from or add heat to the container for an extended period of time so as to maintain a desired temperature of a food or beverage in the container.

The present disclosure embodies a number of aspects that can be implemented separately from or in combination with each other.

A food and beverage server in accordance with one aspect of the present disclosure attaches to the lower portion of a food or beverage container and provides a source of low or elevated temperature surfaces to chill or maintain the chill of a food or beverage within the container, or to heat or maintain elevated temperature of the food or beverage in the container. The attachment means between the server and the container base or sidewall may be fitment: (1) to an existing bead on the container incorporated for some other purpose where the server snaps over that existing bead, (2) a specific bead incorporated only for the snap fitment of the server, (3) threads where the container and the server have mating threads in traditional helical style, or (4) bayonet engagement whereby less than one complete rotation of the server onto the container engages one or more tabs on the server with one or more mating ramps so that the tab(s) provides a friction fit during rotation in opposing directions. The server contains a medium that can be cooled or heated to provide a source to chill or heat at the surfaces of the server. The medium within the server is contained in the bottom or base of the server, within the sidewalls of the server, or both. The low or high temperature surfaces of the server may be concave, convex or flat as needed for facing surface engagement with opposing surfaces of the container.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIGS. 1-4 illustrate a server 10 in accordance with an exemplary embodiment of the disclosure as including an assembly of a container 12 and a thermal core 14 secured to the base of the container. (The term “thermal core” refers to a device that is cooled to chill a food or beverage in the container, or is heated to heat the food or beverage in the container.) Container 12 can be a bottle of glass, plastic or metal construction for example, and includes a body having a sidewall 16, a base 18 and a push-up 20. Base 18 preferably is substantially cylindrical. An external engagement element in the form of a radially outwardly extending shoulder 22 extends around base 18 beneath sidewall 16. The geometry of body 16 as well as the shoulder, neck and neck finish in FIGS. 1-2 are exemplary only.

Thermal core 14 includes a hollow body 24, preferably of plastic construction. Body 24 includes an axially extending annular peripheral wall 26 having an internal bead 28 positioned and sized for snap-receipt over shoulder 22 of container 12. There preferably are a plurality of angularly spaced longitudinal slots 30 in peripheral wall 26 segmenting bead 28 and facilitating radial expansion of wall 26 as bead 28 is snapped over shoulder 22. A central dome 32 of body 24 preferably is sized for heat-transfer facing-contact engagement with the external surface of container push-up 20. Push-up 20 can be somewhat deeper than usual to enhance such heat transfer. Body 24 also has a bottom wall 34 that can be flat or of other suitable geometry such as slightly domed.

A thermal medium 36, such as a fluid medium, is contained within hollow body 24. Medium 36 can be a chillable medium such as a freezable saline solution. A chillable medium alternatively could be a suitable refrigerant, water or another suitable substance. Medium 36 alternatively can be a heatable medium such as sand, oil or a saline solution.

In use, thermal core 14 can be stored in a suitable environment to maintain desired temperature. For example, core 14 can be stored in a freezer or ice chest so that medium 26 is cooled and preferably frozen solid. For use, the thermal core is removed from the freezer or ice chest and assembled over the base of a beer, wine cooler or soda container, for example. As another example, thermal core can be stored in a heated and/or insulated environment. Heat transfer between medium 26 and the contents of the container, through dome 32 and push-up 20, helps maintain a desired temperature of the liquid within the container. The medium-filled cavity of body 24 preferably extends around at least a portion of the base chime area, as best seen in FIG. 2, further to enhance such heat transfer. In addition, bottom wall 34 of thermal core 14 acts as a coaster to help prevent flow of condensate, for example, from the external surface of the container onto a table or the like.

FIGS. 5 and 6 illustrate a server 10 a comprising a thermal core 14 a assembled to the base of a container 12 a. In this embodiment, container 12 a has a cylindrical base 18 a recessed radially inwardly from the container sidewall 16 a. There is a push-up 20 in container 12 a, and a circumferential array of thread segments 22 a on a radially outwardly facing portion of base 18 a beneath sidewall 16 a. Thermal core 14 a includes a hollow plastic body 24 a having an annular peripheral wall 26 a with at least one internal thread segment 28 a for engagement with external thread segments 22 a to retain core 14 a on container 12 a. A suitable medium 36 is contained within hollow body 14 a. Thus, in this embodiment, after chilling or heating, thermal core 14 a can be threaded onto base 18 a of container 12 a.

FIG. 7 illustrates a server 14 b that is similar in many respects to server 14 in FIGS. 1-4 except that the central portion of the plastic body 24 b is concave at 40 for heat-exchange facing engagement with an outwardly extending dome 42 on the base of container 12 b.

FIG. 8 illustrates a server 14 c that has a cylindrical pocket 44 with opposed radially inwardly extending bayonet tabs 46, 48. Pocket 44 of server 14 c provides a flat surface for opposed heat-transfer facing contact with a flat surface 54 on base 18 c of container 12 c. Base 18 c of container 12 c has a pair of helical thread-like engagement elements 50, 52. Thus, server 14 c is adapted to be secured to base 18 c of container 12 c by a bayonet lock arrangement wherein tabs 44, 48 are fitted over and locked to thread elements 50, 52 so that the thermal medium within core 14 c can chill or heat the contents of container 12 c.

FIGS. 9-14 illustrate a server 60 as including a container 62 having a base 64 and an external shoulder 66 adjacent to base 64. A thermal core 68 includes a shell 70 that preferably is of plastic construction. Shell 70 has a circumferential wall 72 with an internal bead 74 adapted for receipt by snap fit over shoulder 66 on container 62. A lateral wall 76 of shell 70 is in engagement with or closely spaced from base 64 of container 62. Shell 70 has a hollow cavity 80 in which thermal material 36 is disposed. Wall 72 of shell 70 can have angularly spaced internal strengthening ribs 86. Bead 74 on shell 70 can be circumferentially continuous, or can be circumferentially segmented as illustrated in FIG. 13.

FIGS. 15 and 16 illustrate a server 60 a that is similar to server 60 in FIGS. 9-15 except that base 64 a of container 62 a has a deep push-up or punt as compared with the relatively shallow dome or push-up base 64. Shell 70 a has a correspondingly contoured wall 76 a for either face-to-face or closely spaced heat-transfer positioning relative to base 64 a.
